摘要：This paper examines the behavior of job seekers and recruiters in the labor market for software engineers. I obtained data from a recruiting platform where individuals can self-report their computer programming skills and recruiters can message individuals they wish to contact about job opportunities. I augment this data set with measures of each individual's previous programming experience based on analysis of actual computer source code they wrote and shared within the open-source software c...

摘要：We study tactical models for the design of same-day delivery (SDD) systems. Same-day fulfillment in e-commerce has seen substantial growth in recent years, and the underlying management of such services is complex. Although the literature includes operational models to study SDD, they tend to be detailed, complex, and computationally difficult to solve, and thus may not provide any insight into tactical SDD design variables and their impact on the average performance of the system. We propose ...

摘要：This paper argues that thresholds in financial contracts act as implicit nudges in consumers' decisions. Exploiting a regulatory change to credit card minimum payments in Mexico, we find that a 1-percentage point change in minimum payments leads to a 0.87-percentage point change in actual payments, both expressed as a percentage of total balances. We decompose the effect of minimum payments into a constraining effect and a reference effect. The former captures the effect of minimum payments as...

摘要：We exploit the staggered passage of state-level fair-employment laws in the post-World War II period to examine how stronger worker protection against racial discrimination affects firm profitability and financing decisions. We find that firms experience a decline in operating profitability after the passage of anti-discrimination laws. We also document that the adoption of these laws leads to a reduction in debt ratios, which suggests that firms are able to partially offset the negative effec...

摘要：This study addresses the ubiquitous challenge of using big observational data to identify heterogeneous treatment effects. This problem arises in precision medicine, targeted marketing, personalized education, and many other environments. Identifying heterogeneous treatment effects presents several analytical challenges including high dimensionality and endogeneity issues. We develop a new instrumental variable tree (IVT) approach that incorporates the instrumental variable method into a causa...

摘要：I study the importance of alpha decay for the measurement of realized and conditional expected returns in asset pricing studies. Alpha decay refers to the reduction in abnormal expected returns (relative to an asset pricing model) in response to an anomaly becoming widely known among market participants. As decreases in alpha are associated (ceteris paribus) with positive realized returns, the econometrician may misinterpret these repricing returns as evidence that the anomaly will persist in ...

摘要：We examine the teams that emerge when a primary care physician (PCP) refers patients to specialists. When PCPs concentrate their specialist referrals???for instance, by sending their cardiology patients to fewer distinct cardiologists???repeat interactions between PCPs and specialists are encouraged. Repeated interactions provide more opportunities and incentives to develop productive team relationships. Using data from the Massachusetts All Payer Claims Database, we construct a new measure of...

摘要：We propose a model of how the retention motive shapes managerial compensation contracts. Once employed, a risk-averse manager acquires imperfectly portable skills whose value is stochastic because of industry-wide demand shocks. The manager's actions are uncontractible, and the perceived fairness of the compensation contract affects the manager's motivation. If the volatility of profits is sufficiently large and outside offers are suffi-ciently likely, the equilibrium contract combines a salar...
